Difference between pulling an image and loading it from tar file

I have a system which uses docker compose.

example docker-compose file:

version: '3'
services:
  base:
    container_name: base
    image: <hub host>/base
    build:
      context: ..
      dockerfile: BaseDockerfile
    environment: 
      - PYTHONPATH=/usr/local/lib/python3.6/site-packages
    volumes:
      - data:/volumes/data/
  postgres:
    container_name: postgres
    image: "postgres:latest"
    ports:
      - 5432:5432

Now, I use this docker-compose file in two different ways - Online and Offline.

In the online mode I run docker-compose build then docker-compose push then ssh to the server I want to deploy it and pull the images and run (docker-compose pull && docker-compose up).

In the offline method I run docker-compose build (same as first one) and then docker save each image to a .tar file then load it using the docker load -i <file name> method, then run docker-compose up

For some reason I get an error (relating to numpy package missfit) in the offline method but not in the server.

I thought there shouldn't be any difference between the methods because they both build the same images and run the containers with the same parameters (that are defined in the docker-compose file).

I tried docker system prune && docker volume prune in all machines that were related to make sure its not a caching issue.

Any ideas as to what the differences between the two methods could be?

EDIT: Saving dockers:

#!/usr/bin/env bash
for image in $docker_hub/base redis postgres
do
    echo "Saving $image"
    docker save $image | gzip > $directory/${image//$docker_hub}.tar.gz
done

image loading:

print "Loading images"
for file in ./*.tar.gz
do
    echo "Loading file: "$file
    docker load -i $file
done

The error I have binary file related:
